I don't know about the south, but the bigger cities in the north seems to be safe. Hargeisa seemed pretty peaceful when I was there the last time and I expect that most of the big cities in Somaliland and Puntland(Garowe,Berbera, Boroma Bosaso, Las Canod?) to be similar.
We arent going to become prosperous any time soon but I can see significant developments happening in the near future, especially in some regions, if things are done right. However, I don't see any significant progress occurring unless alshabab is permanently eliminated from the horn.
